67000 dollars is placed in an account with an annual interest rate of 8.25%. how much will be in the account after 28 years, to

anastassius [24]

Answer:

The Amount of money in the account after 28 years is $616,674.5

Step-by-step explanation:

Given as :

The principal amount placed in the account = p = $67,000

The rate of interest = r = 8.25%

The time period of amount in the account = t = 28

Let the Amount of money in the account = $A

Now<u>, From Compound Interest method</u>

Amount = Principal × $(1+\dfrac{\textrm rate}{100})^{\textrm time}$

A = p × $(1+\dfrac{\textrm r}{100})^{\textrm t}$

Or, A = $67,000 × $(1+\dfrac{\textrm 8.25}{100})^{\textrm 28}$

Or, A = $67,000 × $(1.0825)^{28}$

Or, A = $67,000 × 9.2041

∴ A = $616,674.7

So, The Amount of money in the account = A = $616,674.5

Hence, The Amount of money in the account after 28 years is $616,674.5 Answer

A pool pass costs $30 for the first month and $15 each additional month. Construct an explicit rule in function notation to mode

noname [10]

Answer:

$F(n)=15(n+1)$ [ where $n$ is number of months]

$F(12)=195$

Step-by-step explanation:

Pool pass cost for first month =$30

Pool pass cost after first month = $15 for each month

The total amount charged by the pool can be expressed as a function $F(n)$ where $n$ represents the number of months.

$F(n)=15(n-1)+30$

This can be simplified by using distribution.

$F(n)=(15n-15)+30$

$F(n)=15n-15+30$

$F(n)=15n+15$

Take 15 as greatest common factor.

∴ $F(n)=15(n+1)$

For $n=12$

$F(12)=15(12+1)$

$F(12)=15(13)$

$F(12)=195$

∴ Amount charged by pool for 12 months = $195
